     Thought it was not a good idea to use yum remove .... but had to 
try. In my head I could see you asking me to try it and I should have 
TRIED something, not just sit here. Well, hopefully I can put those 
packages back as you said, tomorrow. Will look for Fraesch book. Thanks 
for the suggestion. Not sure if I'm at runlevel 5 .It's at whatever it 
was set at during the install. Never changed any settings unless told 
to. In the one login I only installed FF, TB, Calc Gimp etc from the 
Applications menu .Entered email addys and bookmarks and logged out 
thinking I'd be OK to get back in again. HA!
